Carapace Size Rostrum overhanging lower edge of incisur at inner end of incisur.

First Antenna: Sensory bristle of 5th joint of adult female with 1 short proximal filament and 6 long terminal filaments, d- and e-bristles of 8th joint well developed filament-like, almost equilength, both with parallel sides and blunt tips.

Furca: Each lamella trapezoidal in shape and with slender bristles between and slightly lateral to main claws.

COMPARISONS.—The only previously described genus in the Cylindroleberidinae with slender bristles between furcal claws is Dolasterope Poulsen, 1965:318 (known only from the type species). Dolasterope differs from Xandarasterope in having the inner end of the incisur rounded, numerous filaments (23 on the type species) on the distal half of the sensory bristle of the 5th joint of the female 1st antenna, 2 bristles on the 2nd endopodial joint of the maxilla, and a triangular furcal lamella.”
